A method of antenna alignment for a wireless mesh communications network (1) is disclosed. The method is applied to a mesh communications network (1) having a first plurality of communications nodes (2) interconnected by a second plurality of wireless communications links (3). The invention discloses a) determining a first set of transmit beam patterns for an antenna array of a first node of the network b) determining a second set of receive beam patterns for an antenna array of a second node of the network c) at the first node of the network, following discovery of the second node of the network by the first node, transmitting an antenna training signal to the second node, using a first transmit beam pattern chosen from the first set of transmit beam patterns d) at the second node of the network, receiving such a transmitted antenna training signal from the first node using a first receive beam pattern chosen from the second set of receive beam patterns, determining a link quality value for such a transmission and storing information relating to the transmit beam pattern, the receive beam pattern and the link quality value, repeating steps (c) and (d) for a predetermined number of combinations of transmit and receive beam patterns. From such stored information determining a preferred transmit and receive beam pattern pair for transmission of data signals from the first node to the second node. |
